To all whom it may concern.-

Beit known that I, GEORGE H. HOLGATE, acitizen of the United States, residing in Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in a Carbureting-Lamp, of which the following is a specification.

This invention relates to certain new and useful improvements in carbureters, and particularly to that class intended to be used in connection with portable apparatus, adapted to use hydro-carbon gases for heating or lightin purposes, and the objects are First. 0 provide an apparatus of the aforesaid character, in compact form, readily portable and of low expense to manufacture. Second. To provide such an apparatus adapted to have fresh charges of gas-producing material inserted without difiiculty. Third. To provide means for the complete control of the air inlet and gas sup ly, whereby the proportions of each may e varied to suit.

ourth. To provide means, whereby the ascending jet of combined air and gaseous vapor is caused positively to rise to the point of ignition. These and other minor objects are attained by the novel combination and construction of parts, hereinafter fully described and shown in the accompanying drawings, in which Figure 1, is a vertical sectional view of the apparatus. Fig. 2, is a transverse sectional view, taken on a line indicated by a-a of Fig. 1, showing, particularly, the air and va- Fig. 3, is a sectional view taken on a line indicated by bb of Fig. 1, showing the openings for controlling the supply of air to the vapor. Fig. 4, is a simi-- lar view taken on a line cc of Fig. 1, showing the port openings for controlling the vapor supply. Fig. 5, is a vertical sectional view of a modification. Fig. 6, is a plan view of the apparatus as shown in Fig. 5. Fig. 7, is a transverse sectional view taken on line dd of Fig. 5, and Fig. 8, is a partial perspective view, showing details of construction.

Like arts are designated by similar characters throughout the several views.

This invention is similar to that disclosed in my former patent 813,796, dated Feb. 27, 1906, but is thought to contain improvement, which I desire to particularize, and claim herein:

The carbureting apparatus may be contained within a font or urn, shaped, proportioned and ornamented to suit the lamp requirements and disposition, or the apparatus casing may be provided with suitable means for disposition directly attached.

In the drawings, the numeral 1, designates the apparatus casing, preferably cylindrical in shape, formed with the bottom closure 2, and provided with the cover 3, having an annular flange 4, fitting over the upper end of the casing 1, and removably connecting thereto. A In the center of the casing is a tube 5, closed at its lower end and secured to the casing bottom 2; its upper end extends through and above the carbureter, terminating in a burner 6, surrounded by a mantle 7 and chimney 8, in the ordinary manner. Also within thecasing concentric to the tube 5, is another tube 9, of greater diameter, forming a space 10, between them, for a current of air. The upper end of the tube 9, reaches to the level of the lower side of the cover 3, while the lower end is provided with an inwardly turned flange 11, to which is attached a screen 12, its outer edge resting upon supports 13.

Within the casing and resting on the screen 12, are a series of annular members 14, made of absorbent material, adapted to be saturated with suitable volatile liquid, said members nested together, but having spaces 15 between each other, roviding for the free circulation of air. bove the absorbent members 14, is a screen 16, which maintains an air space 17 between the screen 16 and the cover 3. A similar air space 18 is provided between the screen 12 and the bottom of the casing 2. The upper screen 16 also positions the upper end of the tube 9, e011- centric to the casing. Fitting the tube 5 and adapted to revolve thereon, is the tube 19, having its lower end extending downwardly to the level of the tube 5, and its upper end reaching through and slightly above the top of the cover 3. Carried by tube 19 are radial arms 20, connecting it to a concentric plate 21, closely fitting the tube 5. One of the arms 20, is extended beyond the plate 21, and carries upon its extreme end, the handle 22, by means of which the said plate and the tube may be revolved. Pins 23 and 24 set in the cover 3, limit the revolutions of the plate and tubes. The tube 19 fills the openmg in the cover 3, and fits the flanged portion at the lower end of the tube 9, in both cases forming air-tight joints, preventing the undesired escape of gas.

In the cover 3 are the openings 25, and in the plate 21, are openings 26, positioned so as to coincide when the handle 22 is operated, so that the arm 20 contacts with the pin 23, the said openings then allowing the maximum supply of air to enter the space 17, thus circulating through and becoming impregnated by the volatile hydro-carbon and passing into the chamber 18, in the form of a hydro-carbon vapor or gas. The lower ends of the tube 5 and 19, disposed within the space 18 are provided with port openings 27 and 28 respectively, and are adapted to register when the handle 22 is moved in the proper direction to open the aforesaid ports, at which time a hydro-carbon vapor from the chamber 18, has free delivery into the tube 5, whereit may be raised direct to the burner 6, by the heat of combustion there taking place, thus inducing a continuous circulation of air through the openings 26 and 25 into the space 17, passing through the saturated absorbent member 14, taking up a portion of the volatile hydro-carbon and entering the chamber 18, in the form of combustible vapor, through the openings 28 and 27 into the tube 5, and to the burner 6. Consequently, after the burner is ignited the combustion of the gas will usually induce the necessary current of air to form sufficient vapor to support continuous combustion. If, however, this draft should prove in suflicient, the auxiliary burner 29, located at the lower end of and immediately below the center tube 5, may be used in addition. Suflicient gas to keep this burner in operation, may be obtained from chamber 18, by the independent tube 30, extending from the bottom 2 of the casing to the burner.

In order to regulate the flame of the main burner, it is necessary to obtain a supply of oxygen with the .vapor, and this is accomplished by providing openings 31 and 32 in the tubes 5 and 19, which are so positioned as to be entirely out of coincidence, when the handle 22 is moved, into the position indicated in Fig. 2, and a full supply of vapor without mixture with air may be obtained.

Pins 23 and 24'are positioned with reference to the several openings, so that when the handle 22 is moved toward the pin 24, from the position as shown in Fig. 2, openings 25 and 26 and openings 27 and 28 gradually close, while openings 31 and 32 grad ually open, thus changing the proportions of vapor and air, when the arm 20 contacts with the pins 24, the openings 25 and 26 and also the openings 27 and 28 are closed, openings 31 and 32 coincide and the supply of all vapor is cut oii, causing combustion to cease.

In place of the burner 29 as shown in Fig. 5, for inducing a draft, use may be made of an entirely independent heater 32, positioned practically as shown in Fig. 1 and readily removable from the apparatus.

I may make use of an outer font or water jacket 35, having a filling nozzle 33, and openings 34 into the carbureter for the entrance of any steam or vapor that may be generated by the auxiliary burner 32. By this means I am able to supply a more uniform degree of heat to the carbureter.

In recharging the apparatus, it is necessary only to remove the burner 6, and its attached parts, lift out the tube 19, and remove the cover 3, whereupon the absorbent members 14 may be saturated with any approved hydro-carbon fluids or combination thereof.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A portable carbureter comprising a case, porous material contained within the case, a tube arranged within the case concentric thereto and stationary therewith, 2. rev oluble member upon said stationary tube, means for imparting a partial revolution thereto, a stationary member concentric to the revoluble tube and having an air space between, openings in the case cover, a revoluble plate adapted to control said openings, and openings in the inner tube and surrounding member adapted to be operated by the revolution of the revolving member, and a heating means located below the central tube, all substantially as shown and described.
